Dallas Mavericks owner Mark Cuban wore jersey No. 46 in the NBA All-Star Celebrity Game on Friday night, and a source told ESPN it was a jab at President Donald Trump in their ongoing long-distance battle, usually waged on Twitter.
Trump is the 45th president of the United States.
On Sunday, Trump had tweeted, "I know Mark Cuban well. He backed me big time but I wasn't interested in taking all of his calls. He's not smart enough to run for president."
That had come after some critical remarks of Trump last week by Cuban, a staunch Hillary Clinton supporter during the presidential campaign.
Cuban was asked by ESPN before the game about his jersey selection and said, "I couldn't get 23. This is two times 23."
Former Chicago Bulls star Michael Jordan made 23 famous.
Cuban unloaded on Trump with a series of six tweets Friday morning.
On Thursday, Breitbart News reported that Cuban had deleted the following tweet after Trump's news conference: "It's time we accept (at)POTUS for who he is. he is entertaining. He is oblivious. He isn't smart enough to be dangerous."
The Mavs owner told ESPN before the celebrity game: "I'm out for a double-double: Ten times up (the court), 10 times down."
